BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented May 23, 1916.

To-aZZ whom it may concern Be it known that I, J OHN PUHL, a c tizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois,

tle closure involving frangible sealing means.

In its preferred embodiment my bottle closure is designed for bluing bottles and embodies as its essential parts a cap member formed with an aperture and having suitable means to engage the neck portion of the bottle whereby to. be held securely in place. Beneath said cap member and clamped by it between the cap member and the open portion of the bottle or receptacle is a frangible sealing disk of suitable material susceptible of being readily punctured, the inner surface of said disk being protected by a protective substance such as a layer of paper or similar material prepared in such a manner as to render the same impervious to the action of water of acids according to the nature of the contents of the receptacle in connection with which the invention is used.

These and such other objects as may hereinafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and claimed.

Reference will now be had to the accompanying drawings forming a part of this specification, wherein a V Figure 1 is a perspective View showing the invention as applied to a bottle type of receptacle. Fig. 2 is a vertical sectional view, the bottle closure being illustrated in normal condition sealing the contents of the receptacle. Fig. 3 is a fragmentary sectional View of the closure portion of the receptacle,

' dotted lines s owing one method of readily puncturing th seal so as to open the bottle and permit of the contents being sprmkled therefrom.

In the drawings A denotes-the bottle or receptacle proper and B the cap member of the closure means.

tle in any substantial manner, and prefer- The said cap member is connected with the neck portion of the bottion which is formed with indentations at intervals in its circumference and such indentations provide projections D capable of engaging with the threaded portion G where'- by to facilitate the screwing action of the cap member upon the neck of the bottle and to thus securely hold the closure means in operative position.

At its central portion the cap member B is formed with the aperture E and beneath the cap member is the sealing disk F and the protective member G. The disk F may be made of card-board or any equivalent substance to'" afford a substantial sealing device. On the other hand the protective memberG is preferably a circular piece of oiled paper or similar substance preferably rendered impervious to the action of water or liquids. Ihe parts F and G are of a diameter fitting snugly within the cap member B, and prevented from accidental dislodgment by means of the projections D.

Since the members F and G are frangible it will be apparent that by the use of a pointed tool, nail or similar device, entered into the receptacle A through the aperture E a hole may be punctured in the parts F and substantially coincident with the opening E andthereupon the contents of the receptacle may be sprinkled or otherwise distributed through such newly made opening. A most convenient means therefore, for rendering the contents of receptacle A distributable is afforded. Furthermore the arrangement of the parts F and G is such that their outermost portions are effectively clamped against the free end of the neck of the bottle and a perfect seal of the contents of the receptacle against. deterioration -or contamination is effectively supplied under these conditions.

Obviously since the materials from which the members F and G are made are such that when punctured whilethe continuity of surface of such materials is of course broken by the aperturingof the same, no portions of the said materialwill fall into the receptacle. In other words, the action of puncturing the members F and G does not cause a separation of any portions thereof from the body of either member and the contents of the receptacle will therefore not receive any such portions of these members, nor is there any likelihood of any such separated portions being created as would cause liability of clogging of the opening E and interfere with its function as an outlet open-. mg.

Having thusdescribed the invention, what I claim as new is:-

As anew article of manufacture, a closure for bottles and like receptacles, the same consisting of a cap member adapted to fit over the neck of the bottle and having means to attach and detach the same to-the neck at will, said cap member being formed with an aperture of a diameter less than that of the bottle neck to which the cap is to be'fitted, a

frangible member of card-board fitting against the under si-de-ofthe'cap *"Inember, and a layer of protective substance consist- 1,1s4,5es

ing of impervious paper removably seated I against the inner side of said frangible memher, the outermost edges of the frangible member and protective substance being adapted to be clamped between the cap member and the end of the bottle neck and thus held firmly to facilitate the puncturing v of said parts but permitting substitution of imperforate protective substance for that punctured as aforesaid.

In testlmony whereof I aflix my signature" in, presence of two*witnesses.

JOHN PUHL.
